\section{ Curious Mappings }
Try \begin{equation}
F_{ij}= \sum _{k=j-i}^{j+i} S_k
\end{equation}
Where $S_k$ is some series, and $j>i$. Will result in a strictly upper triangular matrix. For example for the series $S=1,2,3,4,5...$ we will have the matrix \begin{equation}
\begin{bmatrix}
- & 6 & 9 & 12 \\
- & - & 15 & 20 \\
- & - & - & 28 \\
- & - & - & - \\
\end{bmatrix}
\end{equation}
